Listen to the embedded audio file or video and transcribe the text using the form.
You don't have to transcribe the whole thing at once. Submitting a partial transcription is perfectly ok. You or another native speaker can finish it later.
If a partial transcription exists, please continue where it leaves off. And if you do finish the transcription, please check the Complete? checkbox so that RhinoSpike knows to notify the requesting user and remove the Script Request from the queue.
Transcribing, even partially, moves your own requests forward in the queue.
